How Many Miles per Gallon Does a Dodge Challenger Get?

If you’re eyeing a Dodge Challenger, you’re probably drawn to its bold styling, throaty exhaust note, and muscle car heritage. But let’s be real—fuel economy is a big part of the decision, especially with gas prices fluctuating and daily commutes getting longer. So, how many miles per gallon does a Dodge Challenger really get?

The short answer? It depends. A lot. The Challenger isn’t a one-size-fits-all car. With multiple engine options, from a fuel-sipping V6 to a fire-breathing supercharged V8, your fuel economy can swing from 13 mpg to 30 mpg depending on what’s under the hood—and how you drive it.

In this guide, we’ll break down the real-world fuel efficiency of every major Challenger trim, explain what affects your MPG, and share practical tips to squeeze every mile out of each gallon. Whether you’re considering the base SXT, the track-ready SRT Hellcat, or something in between, you’ll know exactly what to expect at the pump.

Understanding the Dodge Challenger’s Engine Lineup

To understand fuel economy, you first need to know what’s powering your Challenger. Dodge offers a range of engines, each with its own personality and fuel appetite. Let’s walk through the main options.

The 3.6L Pentastar V6 Engine

The base engine in the Dodge Challenger SXT and GT trims is the 3.6L Pentastar V6. This engine produces around 305 horsepower and 268 lb-ft of torque—more than enough for daily driving and highway merging. It’s paired with an 8-speed automatic transmission and comes standard with rear-wheel drive.

This engine is the most fuel-efficient in the lineup. According to the EPA, the V6 Challenger delivers up to 19 miles per gallon in the city and 30 on the highway, with a combined rating of around 23 mpg. That’s not bad for a car that weighs over 4,000 pounds and still offers a sporty feel.

Real-world drivers often report slightly lower numbers—closer to 17–18 city and 28–29 highway—due to traffic, weather, and driving habits. But for a muscle car, that’s impressive.

The 5.7L HEMI V8 Engine

Step up to the R/T trim, and you get the legendary 5.7L HEMI V8. This engine cranks out 375 horsepower and 410 lb-ft of torque, giving the Challenger a serious punch. It’s available with either a 6-speed manual or an 8-speed automatic.

The trade-off? Fuel economy takes a noticeable hit. The EPA rates the 5.7L V8 at 16 mpg city and 25 mpg highway, with a combined average of 19 mpg. That’s still respectable for a V8-powered coupe, especially one with this much character.

One fuel-saving feature in the automatic version is MDS (Multi-Displacement System), which deactivates four cylinders under light load to save gas. It’s not perfect—some drivers notice a slight hesitation when the system kicks in—but it helps stretch your tank a bit farther.

The 6.4L HEMI V8 Engine

For those who want more muscle, the R/T Scat Pack and SRT 392 trims come with the 6.4L HEMI V8. This beast delivers 485 horsepower and 475 lb-ft of torque, launching the Challenger from 0 to 60 mph in under 4 seconds.

But all that power comes at a cost. The EPA estimates 13 mpg city and 21 mpg highway, with a combined rating of 16 mpg. That’s a significant drop from the V6, especially in stop-and-go traffic.

Still, for weekend warriors and track-day enthusiasts, the performance is worth the extra fuel stops. And like the 5.7L, the 6.4L uses cylinder deactivation in automatic models to improve efficiency during cruising.

The Supercharged 6.2L HEMI V8 (SRT Hellcat and Redeye)

Now we enter the realm of supercar territory. The SRT Hellcat and Hellcat Redeye trims are powered by a supercharged 6.2L HEMI V8 that produces a jaw-dropping 717 to 797 horsepower. These cars are built for straight-line speed, not fuel economy.

The EPA ratings reflect that: 12 mpg city and 21 mpg highway for the Hellcat, and 13 mpg city / 21 highway for the Redeye. Combined, that’s around 15–16 mpg. In real-world driving, especially with spirited acceleration, you might see single-digit mileage in the city.

But let’s be honest—if you’re buying a Hellcat, you’re not doing it for the gas mileage. You’re doing it for the roar, the acceleration, and the bragging rights. Still, it’s good to know what you’re getting into.

Real-World Fuel Economy: What Drivers Actually Experience

EPA ratings are a great starting point, but they don’t always reflect real-world driving. Let’s look at what actual Challenger owners are reporting.

City Driving: The Biggest MPG Drop

In city driving, especially in heavy traffic, fuel economy drops across the board. The V6 might dip to 15–16 mpg, while the 5.7L V8 could fall to 13–14 mpg. The 6.4L and Hellcat models often see single-digit mileage if you’re frequently accelerating hard or idling.

Why? Stop-and-go driving prevents engines from operating efficiently. Every time you brake, you lose momentum, and every time you accelerate, you burn extra fuel. Add in air conditioning, stoplights, and traffic jams, and your MPG takes a hit.

One owner of a 2022 Challenger R/T reported averaging 14.5 mpg in city driving over a 3,000-mile period. “It’s not great,” he said, “but I knew what I was getting into. I drive it like a muscle car.”

Highway Driving: Where the Challenger Shines

On the highway, the Challenger performs much better. The V6 can easily hit 28–30 mpg at a steady 65–70 mph. The 5.7L V8 often reaches 24–26 mpg, and even the 6.4L can manage 19–21 mpg if you keep your foot light.

Cruise control helps a lot here. By maintaining a constant speed, you avoid unnecessary acceleration and braking, which improves efficiency. One GT owner reported 29.5 mpg on a 400-mile highway trip—just 0.5 mpg below the EPA estimate.

Mixed Driving: The Real Test

Most drivers don’t live in pure city or highway environments. Mixed driving—commuting, errands, weekend trips—gives a more accurate picture.

For the V6, expect 18–22 mpg combined. The 5.7L V8 typically averages 16–19 mpg. The 6.4L lands around 14–17 mpg, and the Hellcat models hover between 12–15 mpg.

These numbers align closely with EPA estimates, but they can vary based on driving style, terrain, and vehicle load.

Factors That Affect Your Challenger’s Fuel Economy

Your MPG isn’t just about the engine. Several factors influence how efficiently your Challenger uses fuel.

Driving Habits

How you drive has a huge impact. Aggressive acceleration, hard braking, and speeding can reduce fuel economy by 15–30%. For example, flooring it from a stoplight might feel great, but it burns fuel like crazy.

Smooth, gradual acceleration and anticipating traffic can make a big difference. One tip: ease into the throttle instead of stomping it. You’ll still get moving quickly, but you’ll use less gas.

Also, avoid “jackrabbit starts”—those quick launches that make the tires chirp. They’re fun, but they waste fuel and wear out your tires faster.

Vehicle Load and Aerodynamics

The more weight your car carries, the more fuel it burns. Roof racks, heavy cargo, and even passengers add up. Removing unnecessary items from the trunk can improve MPG by 1–2%.

Aerodynamics matter too. The Challenger isn’t the most aerodynamic car, but you can help. Keep windows up at highway speeds—open windows increase drag. And avoid adding large spoilers or body kits unless you need them for performance.

Tire Pressure and Maintenance

Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure monthly and keep it at the recommended level (usually 32–35 psi). You can find the correct pressure on a sticker inside the driver’s door.

Regular maintenance also plays a role. A dirty air filter, worn spark plugs, or old oil can reduce engine efficiency. Follow the manufacturer’s maintenance schedule to keep your Challenger running smoothly.

Climate and Weather

Cold weather reduces fuel economy because engines take longer to warm up and batteries work harder. In winter, you might see a 10–20% drop in MPG, especially for short trips.

Using the heater, defroster, and seat warmers also draws power from the engine, which can increase fuel consumption. Try to limit their use when possible.

Fuel Type and Quality

Dodge recommends premium fuel for V8 models, especially the 6.4L and supercharged engines. Using regular gas can cause knocking and reduce performance, which may hurt efficiency over time.

Even for the V6, using high-quality fuel with detergents can help keep fuel injectors clean and improve combustion.

Tips to Improve Your Challenger’s Fuel Economy

Even if you drive a V8, you can take steps to improve your MPG. Here are some practical tips.

Drive Smoothly

Avoid rapid acceleration and hard braking. Use cruise control on the highway. Anticipate stops and coast when possible. These habits can improve your mileage by 10–20%.

Use the Right Gear

If you have a manual transmission, shift early and avoid revving the engine unnecessarily. For automatics, let the transmission shift on its own—don’t “power brake” or hold the car on a hill with the gas.

Reduce Idling

Idling burns fuel without moving you anywhere. If you’re stopped for more than 30 seconds (except in traffic), turn off the engine. Modern cars use less fuel to restart than to idle for long periods.

Keep Up with Maintenance

Replace air filters, spark plugs, and oxygen sensors as recommended. Use the correct oil grade—Dodge recommends 5W-20 or 5W-30, depending on the engine. Clean oil reduces friction and improves efficiency.

Lighten the Load

Remove heavy items from the trunk. Avoid carrying unnecessary cargo. Every 100 pounds reduces fuel economy by about 1%.

Plan Your Trips

Combine errands into one trip instead of making multiple short drives. A warm engine is more efficient, so fewer cold starts mean better MPG.

Comparing the Challenger to Competitors

How does the Challenger stack up against other muscle cars and performance coupes?

Ford Mustang

The base Mustang with the 2.3L EcoBoost four-cylinder gets 21 city / 32 highway mpg—better than the Challenger V6. The 5.0L V8 Mustang GT gets 16 city / 25 highway, similar to the Challenger R/T.

But the Mustang is lighter and more aerodynamic, which helps its efficiency. Still, the Challenger offers more interior space and a smoother ride.

Chevrolet Camaro

The Camaro 1LT with the 2.0L turbo four-cylinder achieves 22 city / 31 highway mpg. The 6.2L V8 SS model gets 16 city / 24 highway—again, comparable to the Challenger R/T.

The Camaro is more agile and track-focused, but the Challenger wins in comfort and daily usability.

BMW 4 Series

For a luxury alternative, the BMW 430i gets 26 city / 35 highway mpg. It’s more efficient, but it lacks the raw muscle car character of the Challenger.

If fuel economy is your top priority, a German coupe might be a better fit. But if you want American muscle with a side of efficiency, the Challenger V6 is a strong contender.

Is the Dodge Challenger Worth It for Fuel-Conscious Buyers?

So, should you buy a Challenger if you care about gas mileage?

It depends on your priorities.

If you want maximum efficiency, the V6 SXT or GT is your best bet. With up to 30 mpg on the highway, it’s surprisingly economical for a car this size and power. It’s perfect for daily driving, road trips, and even light track use.

If you crave V8 power but still want decent mileage, the 5.7L R/T is a great compromise. It’s not a fuel-sipper, but it’s not a gas guzzler either—especially with cylinder deactivation.

The 6.4L and Hellcat models are for enthusiasts who value performance over economy. If you’re okay with frequent fill-ups and higher fuel costs, they’re worth every penny.

Ultimately, the Challenger proves that muscle cars can be practical. With the right engine and driving habits, you can enjoy the thrill of American muscle without breaking the bank at the pump.
